Corsair was able to increase the frequency of its DDR3 modules, which is very high anyway, even further and thus set a new world record.
With a validated memory frequency of 2,533 Megahertz and sharp timings of 7-8-7-20 Corsair was able to overclock the 2,000er modules of the Dominator GT series quite impressively. For the new record attempt only high-end hardware was used. The test system was powered by an 1,000 watt Corsair PSU (HX1000W) and a 256 GB SSD (P256) was used to store the data. A Core i7 Extreme 975 - which isn't available to customers yet - was placed on a EVGA X58 3X SLI Classified, which is regarded to be one of the best overclocking motherboards available at the moment.
Besides the high frequency this record is also interesting because of another reason. Usually only one memory module with an capacity of one GiByte is used for world record attempt, but Corsair was able to reach the results with three 2 GiByte modules. What kind of cooling solution was used or the applied voltage has not been revealed by Corsair, but it is estimated that the recently introduced memory water cooler was used to deal with the increased heat.
